TOY CANNON.

Application ined July 11,

vention resides in thedetails of construction of the magazine of the gunwhereby the same is formed up and completed,simultaneously witheffecting its rigid association with the gun barrel.

The invention, inits preferred embodiment, is fully illustrated in theaccompanying drawings, wherein z-f Figure 1 is a central verticallongitudinal section of a magazine gun constructed in accordance withthe invention.

Figure 2 is a similar view showing the gun plunger' drawn backpreparatory to release thereof to eject a projectile.

Figure 3 is a fragmentary top plan view of the gun and its magazine.

Figures 4 and 5 are vertical transverse sections .on the lines 4 4 and5-5 respectively, of Figure 1.

Figure 6 is a perspective view of a projectile for the gun.

Figure 7 is a plan view of a sheet metal blank of which the magazine ismade.

The gun comprises the barrel 1 having a cylindrical bore 2 closed at oneend by means of the breech-block 3 which may be composed of wood, corkor other material, the gun barrel being preferably made of wood.

In the breech-bloclr 3 isa central opening.

axially coincident with the bore 2 and through which one end portion ofthe plunger 4 passes freely, said plunger being provided between itsends with an annular enlargement 5 substantially fitting. the bore 2. Ahelical compression spring 6 `is interposed between the portion 5 of theplunger and the breechblock 3. The outer end of the plunger 4'isequipped with a handle element 7 whicliis cylindrical and is providedbetween un amis with an annular garen-ve a to permit tion, the lateraland longitudinal dimensions 1927. Serial No. 204,750.

the same to be easily digitally engaged for drawing back against theaction of the spring 6 as shown in Figure 2. The outer end of theplunger 4 enters a central bore in the element 7 and is preferablysecured to the latter by means of the key-pin 9.

The gun barrel 1 is provided between its ends in the uppermost portionof its cir` cumferential wall with a longitudinal slot `1() throughwhich the projectiles 11 enter the bore 2. Fitted to the barrel 1 is atubular magazine 11 made preferably of sheet metal and which is ofrectangular cross-secof said magazine 11 being such that the lower vendsof the end walls thereof fit snugly telescopically within the slot 10 atthe ends of the latter.` The side walls of said member 11 are providedmidway 'between their side edges with longitudinal indentations formingribs 12 interiorly of the tube 11, the

lower ends of said ribs providing projections 13 which extend into theslot 10.

The said magazine member is composed of a single piece of sheet metalwhich, as shown in Figure 7, illustrating the blank before forming,comprises two side wall portions `14 and 15 respectively, connected witheach other by intermediate strap-portions 16 spaced from each other bythe longitudinal slot 17. The vportion 14 is of such greater width thanthe portion 15 as to include the end-wall port-ions 18 adapted to bebent at right angles to the middle portion thereof along the dottedlines 19. At the side edges of the portion 14 are two pairs of lugs orflanges 2O andV at the side edges of the portion 15 is one pair `of lugsor flanges 21 all of said lugs or flanges being bent to extend at rightangles to the `adjoining side edge j portions of saidk portions 14 and15 of the blank` after the latter is bentto cause the saidv portions tobecome opposed to each other to form the tube 11, the lugs or flanges 20then overlapping the outer faces of the portion 15 and the lugs orflanges 21 then overlapping the end wall portions of the portion 14 ofsaid blank to thereby securely lock the walls of the tube 11 againstrela- 100 tive displacement. It will be understood,

of course, that the'. rib forrlrziations are pro@ ltl end- 'alls are`sprung into the slot 1t) o'l the4 barrel. The several lugs or flanges2O and 21 are then bent as above described to com-k plete the magazinetube 1l and. at the same time, secure the same rigidly to the gunbarrel. The latter is provided with an annular shallow groove to receivethe said strap-portions 1G, the outer side edges of which engage theannular shoulders at the ends ot' .said grooves to prevent longitudinalmovement of the magazine relativelyY to the gun barrel.

At the upper ends ot the ribs 12 I provide indentations which formopposed projections Q5 spaced from cach other a distance slightly lessthan the diameter of the middle or annular groove portions Q4 of' the cvlindrical projectiles 25, the end portions ot which are of a diameter,slightly less than that of the bore 2 ot the gun barrel 1, the totallength ot each projectile heilig somewhat less than the longer diameterotv the magazine 11j.I the ribs 12 ot the latter preventing the ends ofthe projectiles from coming into contact with the end walls ot themagazine to thereby more efl'cctually prevent canting of saidprojectiles.

The operation ol` the device will be very readilj7 understood withoutfurther description.

I claim as m v invention:

1.The combination with a gun barrel having a longitudinal slot betweenits ends, ot a magazine tube mounted on said barrel and communicatiiigat its discharge end with said slot'` inwardly extending guideformations on opposed walls of said tube` and .projectiles provided withguide formations between their ends for cooperation with the formationsot said tube to prevent canting ot said projectiles.

Q. A magazine tube tor the purpose speeirectangular in cross-section,opposed walls ot said tube provided with longitudinal guide formations,and project-iles provided between their ends with cooperating guideformations adapted to Cooperate with the formations of said tube toprevent canting ot said projectiles.
